How do I know if all libraries are correct? If camera is not busy, it works. So I suppose, libraries are correct. Does it work for you?

not sure if I'm doing it right, python still crashes before cc = VideoCapture()

    cam = VideoCapture()
    success = False
    if not cam.isOpened():
        success = cam.open(0)

    if success: 
        ok, img = cam.read()

it also crashes before cam = VideoCapture(0)

it fails on release(). I can see the print output before it

if cam.isOpened(): print "release" cam.release()

Thx. I've tried that, but it still crashes.

Hello,

is there a way to check if webcam is busy before taking an image? Python.exe would crash if camera is in use and following code is running

Python code:

from cv2 import *
while True:
    #need to check here if camera is busy
    cam = VideoCapture(0)
    s, img = cam.read()
    if s:    # frame captured without any errors
        imwrite("filename.jpg",img) #save image
